alleryWhich of these is NOT a colligative property?
ABoiling point elevation
BFreezing point depression
COsmotic pressure
DDensity of solution
Answer & Solution
Correct answer: D. Density of solution
**The 4 colligative properties:**
(1) Relative lowering of vapour pressure,
(2) Boiling point elevation,
(3) Freezing point depression,
(4) Osmotic pressure.
Density depends on the nature of the solute, NOT just the number of particles, so it is NOT colligative.
